Switch Device With Detachable Operating Mechanism Shaft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic transfer switches have integrated shafts that prevent the operating mechanism from being disassembled independently, making maintenance cumbersome and costly, as power supplies must be cut off for repairs.
Innovation Solution
A switching apparatus with separate main shafts for the operating mechanism and switching component, allowing the operating mechanism to be detached while maintaining the switching state, using a locking member and elastic element to secure the first main shaft's position and facilitate secure fastening and electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an integrated main shaft is used to connect the operating mechanism to the poles, then the switching apparatus has a compact structure, but the operating mechanism cannot be disassembled independently for maintenance
Solution Approach 1:
The patent divides the integrated main shaft into two separate shafts: a first main shaft connected to the switching component and a second main shaft connected to the operating mechanism. These separate shafts can be independently disassembled and reassembled, allowing the operating mechanism to be maintained without affecting the switching component, thus resolving the contradiction between compact structure and ease of repair.
2Ease of repair
If the operating mechanism is disassembled from the switching component, then maintenance can be performed, but the switching state may change
Solution Approach 1:
The patent employs a locking member that locks the first main shaft in a specific rotation position corresponding to the switching state before disassembly. This preliminary locking action ensures that when the operating mechanism is disassembled and reassembled, the switching state is preserved, thus resolving the contradiction between maintenance capability and switching state stability.
3Ease of repair
If power supplies are cut off for maintenance, then the switching apparatus can be safely repaired, but operational disruptions occur
Solution Approach 1:
The patent allows the operating mechanism to be separated from the switching component, enabling maintenance of the operating mechanism while the switching component remains connected and operational. This segmentation enables safe maintenance without cutting off power supplies, thus resolving the contradiction between safe maintenance and operational continuity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables maintenance without disrupting power supplies, reducing maintenance costs and improving maintenance efficiency by allowing the operating mechanism to be detached and reattached without altering the switching state, thus minimizing downtime and operational disruptions.
Implementation Method 1
an elastic element is coupled to the locking member for driving the locking member to move from the locking position to the release position in response to a release of the operating member
